[jira] [Created] (SPARK-29468) Floating point literals produce incorrect SQL

Jose Torres created SPARK-29468:
-----------------------------------

             Summary: Floating point literals produce incorrect SQL
                 Key: SPARK-29468
                 URL: https://issues.apache.org/jira/browse/SPARK-29468
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 2.4.4
            Reporter: Jose Torres


A FLOAT literal 1.2345 returns SQL `CAST(1.2345 AS FLOAT)`. For very small values this doesn't work; `CAST(1e-44 AS FLOAT)` for example doesn't parse, because the parser tries to squeeze the numeric literal 1e-44 into a DECIMAL(38).
